Re: "dosser'

: I heard this in a song lyric. "Just one old "dosser" lurching down Oxford Street, to spend his Christmass lying in the rain." What is a "dosser?" Thanks.

Perhaps you heard "tosser" a UK insult (not used in the US) for a masturbator, loosely meaning a worthless person. "Wanker" is similar, also not heard in the US. The American equivalents are "jerk" or "jerkoff" with roughly the same level of insult and/or vulgarity.
